1974 Valiant Scamp, timing retarding when revved

I haven't been able to get to the bottom of the timing issue yet and feel like it may be partly due to a poorly set up carb. Once it warms up I can't put it in gear without stalling, got myself stuck in the middle of the road for a bit...that was fun. It is an Edelbrock 1406 with what look like plain colored springs. I can't read the jets or rods, but I'll try to get the numbers tomorrow. I ripped the carb off and started a rebuild since I don't know the history, but I do know it was not originally on this car. I also noticed the accelerator pump was set to the lowest hole, or weakest shot. I got a short video of the idle, which sounds horrible, and then the part throttle stumble (you can see the battery and motor shaking), as well as the lag in quick throttle transitions.
